中文摘要	2-furyloxirane (fo), a monomer usually obtained from a nonpetroleum route, was prepared from the epoxidation reaction of furfural and trimethylsulfonium chloride. about 200-300 g fo can be obtained in each preparation process. although anionic polymerization of fo generally gives low-molecular-weight polymers even after long periods of polymerization, the reaction was greatly improved when macrocyclic ether was used as a cocatalyst to potassium tert-butoxide. when 18-crown-6 was used as a cocatalyst, poly(2-furyloxirane) (pfo) with a number-average molecular weight (m(n)) of 41.5 kg/mol and a polydispersity index of 1.3 was obtained at 94% yield after polymerization at 40 degrees c for 72 h. the pfo obtained contained a 61.7% head-to-tail (h-t) structure in the absence of the macrocyclic ether, and it reached 70.6% when cryptand[2,2,2] was used as a cocatalyst. pfo with higher regioregular structures showed improved thermal properties. for pfo with m(n) of around 20.0 kg/mol, its glass transition temperature (t(g)) increased from -3 to 6 degrees c when the h-t content was increased from 61.7 to 70.6%. raising the m(n) of pfo also raised t(g). for pfo with 68.9% h-t structure, its t(g) could reach 7 degrees c when m(n) was increased to 40 kg/rnol. this study shows two effective ways to improve the thermal and mechanical performances of the polymer.
